For Apollo's openwire impl (and i'm assuming it's the same for amq), when a
client opens a connection to the broker, the sequence of commands that are
sent goes like this:
1) Client --- WireFormatInfo ----> Broker
2) Broker --- WireFormatInfo ----> Client
3) Broker --- BrokerInfo ---> Client
4) Client --- ConnectionInfo ---> Broker
Is that correct? Or is 3 and 4 swapped? or are 3 and 4 async and can happen
in any order?
